Tools & Gear Taps & Dies HSS Hand and Machine Taps

HSS Straight Flute Short Machine and Hand Taps These general purpose taps are ideal for creating new threads in a wide variety of materials. Goliath HSS taps provide a high hardness to toughness ratio - compressive and tensile strength - good abrasion resistance and resistance to micro-chipping - ensuring a long tool life. UNEFUNIFIED NATIONAL EXTRA FINE UNEF is a subset of UNF in which the thread forms feature a greater number of TPI than the standard UNF series. TAPER TAPS have a lead of eight threads and are used as a starting tap in difficult or high precision holes. INTERMEDIATE TAPS have a lead of four threads and are used in most general purpose applications to cut a thread true to a pre-drilled pilot hole. BOTTOMING TAPS have a lead of two threads and are used to ensure minimum thread run-out when tapping to the bottom of a blind hole. Bottoming Taps are typically preceded by the use of a Taper or Intermediate Tap. Manufactured from HSS this general purpose tap is designed for use in medium tensile materials and is for hand or general machine use.
